[0043] With particular reference still to FIG. 7, the button member 140 of the locking mechanism 130 includes first and second legs 140a, 140b each defining a slot 141a, 141b, respectively. The button member 140 is configured to be received about the upper band guide 132 of the locking mechanism 130 such that the first and second legs 140a, 140b of the button member 140 are received within respective first and second cutouts 145a, 145b of the upper band guide 132 and the first and second tabs 146a, 146b (FIG. 8) of the upper band guide 134 are received within the respective slots 141a, 141b.
[0044] The operation of the locking mechanism 130 of the adapter assembly 100 will now be described with reference to FIGS. 8-16. Referring initially to FIGS. 8-13, the locking mechanism 130 is shown in the locked configuration, i.e., with the first and second locking blocks 136, 138 in their first position. In particular, the first locking block 136 is supported on the first cam post 150a of the upper band guide 132 and the first cam post 160b of the lower band guide 134 and the second locking block 138 is supported on the second cam post 150b of the upper band guide 132 and the second cam post 160b of the lower band guide 134. The first and second locking blocks 136, 138 are biased radially inward by respective first and second springs 142a, 142b to the first, locked position (FIG. 12).
[0045] The trocar assembly 120 of adapter assembly 100 may be provided preloaded within sleeve 106 of the adapter assembly 100, or the trocar assembly 120 may be provided separated from the adapter assembly 100. If provided as a separate component, the trocar assembly 120 is loaded through a distal end of the sleeve 106 of the adapter assembly 100 prior to attaching an end effector, e.g., the end effector 30, to the connector housing 108 of the adapter assembly 100. The trocar assembly 120 is fed into the sleeve 106 of the adapter assembly 100 between the first and second locking blocks 136, 138 to cam the first and second locking blocks 136, 138 outwardly against the bias of springs 142a, 142b until alignment of the first and second locking blocks 136, 138 with the first and second locking slots 123a, 123b of the outer housing 122. An audible and/or tactile indication may be provided to a user by the locking mechanism 130 as the first and second locking blocks 136, 138 are received with the respective first and second locking slots 123a, 123b to indicate that the trocar assembly 120 is securely received within the locking mechanism 130.
[0046] During loading of the trocar assembly 120 through the locking mechanism 130, the button member 140 of the locking mechanism 130 may be depressed to move the first and second locking blocks to the second or unlocked position (FIG. 14) to facilitate loading of the trocar assembly 120 between the first and second locking blocks 136, 138, and within the sleeve 106. Alternatively, engagement of the first and second locking blocks 136, 138 by the outer housing 122 of the trocar assembly 120 as the trocar assembly 120 is loaded through the locking mechanism 130 will maintain the first and second locking blocks 136, 138 in their second position until the first and second locking slots 123a, 123b of the outer housing 122 align with the respective first and second locking blocks 136, 138. Upon alignment of the first and second locking blocks 136, 138 with the respective first and second locking slots 123a, 123b, the first and second locking blocks 136, 138 are biased into the first and second locking slots 123a, 123b, respectively.
[0047] In embodiments, the outer housing 122 of the trocar assembly 120 includes internal flat portions 125 (FIG. 11) for maintaining rotational alignment of the trocar assembly 120 relative to the locking mechanism 130 to ensure that the first and second locking slots 123a, 123b of the trocar assembly 120 are maintained in alignment with the respective first and second locking blocks 136, 138 of the locking mechanism 130.
[0048] Engagement of the first and second legs 140a, 140b of the button member 140 of the locking mechanism 130 with the respective first and second locking blocks 136, 138 maintains the button member 140 in an outward, non-depressed position. Receipt of the first and second button retainer tabs 146a, 146b within respective slots 141a, 141b of the first and second leg
140a, 140, respectively, of button member 140 maintains the button member 140 in engagement with the upper band guide 132 of the locking mechanism 130.
[0049] As noted above, the upper and lower band guides 132, 134 each include strain gauge retainer portions 152, 162, respectively, for supporting the strain gauge 170. The trocar assembly 120 of the adapter assembly 100 is received through the strain gauge 170. The strain gauge 170 is configured to measure deflection and/or movement of the trocar assembly 120 during operation of the adapter assembly 100. The first and second flexible bands 112a, 114a of the inner and outer flexible band assemblies 112, 114 of the drive assembly 110 are received through the longitudinal recess 143 of the upper band guide 132 and the first and second flexible bands 112a, 114b of the inner and outer flexible band assemblies 112, 114 are received through the longitudinal recess 153 of the lower band guide 134.
[0050] Once the trocar assembly 120 is loaded with the sleeve 106 and secured therein by the locking mechanism 130, the adapter assembly 100 and the attached handle assembly 20 (FIG. 1), the loading unit 30, and the anvil assembly 40 (FIG. 1) operate in a traditional manner.
[0051] Following a surgical stapling procedure using the surgical stapling device 10, the trocar assembly 120 of the adapter assembly 100 is removed from the sleeve 106 of the adapter assembly 100 to facilitate cleaning and/or sterilizing of the adapter assembly 100.
[0052] With reference to FIGS. 14-16, the locking mechanism 130 of the adapter assembly 100 is shown with the first and second locking blocks 136, 138 in a second or unlocked position. When the first and second locking blocks 136, 138 are in the second position, the trocar assembly 120 is removable from within the sleeve 106 of the adapter assembly 100.
[0053] With particular reference to FIG. 14, the first and second locking blocks 136, 138 are moved to the second position by depressing the button member 140 of the locking mechanism 130 radially inward, as indicated by arrow "A" in FIG. 14. As noted above, the first and second leg portions 140a, 140b of the button member 140 engage an upper surface of the respective first and second locking blocks 136, 138. When the button member 140 is depressed, engagement between the first and second leg portions 140a, 140b of the button member 140 with the respective first and second locking blocks 136, 138 moves the first and second locking blocks 136, 138 downwardly about the cam posts 150a, 160a and 150b, 160b against the bias of the first and second springs 142a, 142b, respectively. The first locking block 136 rides along the first cam post 150a, 160a of the upper and lower band guide 132, 134, respectively. Because of the configuration of the cam slots 131a, 131b, the first locking block 136 moves in a radially outward direction, as indicated by arrow "B" to the second position. Similarly, the second locking block 138 rides along the second cam post 150b, 160b of the upper and lower band guide 132, 134, respectively. Because of the configuration of the cam slots 133a, 133b, the second locking block 138 moves in a radially outward direction, as indicated by arrow "C", to the second position.
[0054] As the first and second locking blocks 136, 138 are moved to their second position, the first and second locking blocks 136, 138 are moved from within the respective first and second locking slots 123a, 123b of the trocar assembly 120 and the clearance portions 135a, 135b of the respective first and second locking blocks 136, 138 are aligned with the trocar assembly 120. In this manner, the trocar assembly 120 is no longer secured by the locking mechanism 130. The trocar assembly 120 may then be removed from within the sleeve 106 of the adapter assembly 100.
